w'cilicalion forming part of Letters Patent No. 29.053. dab-d July I", l-ld main frame, platform, and driving wheel; and,

secondly, to an arrangement and combination. ol'a discharging-rake, with the platlormand hack-action rake and the operating mechanism,

of the horizontal shaft of the rake-aback, is a as hereinafter fully described. v a

To enable others skilled in the'art to make and use my invention, I will proceed to-atate the manner at its construction and the mode ol'its operation. Y

in my original invention the power to operate the rake was communicated hythe main 1 shall through a crank to an arm or lever attaehedto said crank and also toa sleeve which moved on a slide connected in front to the crank-shall, which sleeve was also connected to another arm or lever, whiclrwas at its oppusile end connected to aireighth-arm ot' the sweep-post. therein but in this invention, which in this respect is an improvement upon my former one, the power for operating the rake is communicated by a cogged wheel on the interior end of the main shaft through another similar wheel on aerank-shat't to an arm or pitninn connected with said crank at one end and to an eighth-arm of n. aweeppoat at the olht'l' end, said sweep-post being placed on the rear interior corner of the main 'i'rame ot the machine.

In the drawings, the letter A represents the wheel on the nmiu shaft; letter 1!, the wheel on the crank-shaft; letter C, the crank, and the letter 1) the arm or pitman; the letter E, thoewcep-post, and the letter 1 the eightharm therein. I

lly thisinrention the power to move the rake is applied in the most direct manner and thereby avoids the complex machinery of the said first invention and tends to cheapen the coat of the machine. The sweep-post has a gyrobet'ore mentioned, whereby another arm thereoi, which is angular in shape and is designated by the letter F, is caused to move circularly with the motion of the swoop-post. The arm F, with itsangle,occupier-an horizontal position and the outer partot' this angular arm sustains in boxes the horizontal shaftol'the rakeshnnk, and in marked. The head of the rake is made of iron and has a crank connected with it of the same materiah The rake-head is designated by the letter ll, and thecr'ank thereof is inclined upwardly from the rake-head when the rake is at rest, and is connected with the horizontal ahal't before mentioned. The inclined shank is marked by the letter I on the drawings.

On the arm- 1 of the sweep-post, and in rear latch and spring, and on the lower side of said part of said shanlgbnt outside-oi the box, near the angle, is a piece of casting, in which is a catch, (marked 0,) and on the lower side of the inclined crank ot'the shank of the rake (marked l) in Mixed a plate ofmeta'l of nearly triangular shape, and on a bar of metal that passes over the sweeppoat and is bent down toward the linger-beam or platform is a roller, against which the triangular piece of metallic plate strikeeandover which it riscst'or the deliveryot' its gavel, and also to admit of the action of the latch, no nearly similar to such devices for like purposes in my former invcntitmthat a reference to the specification in that case is made for them and their principle of action. The rakehead is furnished with a divider-frame, made of small bars or rods of iron and is of rectangular shape. it is l'aatened to the rakehead by screw-bolts passing through the lower side of the frame into the rake-head, and by a brace from the inclined crank of the knack of the rake to near the top of the. end thereof nearest to the driving-w heel, and said brace is fastened to said rake-frame and to the inclined crank by screw-bolts. The frame for the rakehead is intended. to divide the falling grain from the gavel about to be removed, and'ia placed in a position on said rake-head inclining backwardly therefrom at an angle of about forty-tire degrees, and it is covered with a dirider 0t enameled or painted cloth, which as the rakeismade to reeedc with a gavel, will permit the falling grain to slip easily to the platform. The brace aforesaid iedesignated .by the letter b, and the divider and its frame are designated by the letter d. it is evident that W 1 race b" \vill-s'crve also to prevent the falliog grainfrom getting out of positionon the rake or its divider, and that a cloth or other material fastened to the brace on one side and to the diridenframo and the crank lot the 'sbankof the rake will. also serve to prevent short grain-4s cats or barley-from being wasted b'yslipping off of that end of the rakedivider. It is alsoobvions that the action of the rake might be'made more effective by using the spiral spring on the horizontal part of the shaft thereof, as set forth in my said former invention, a

The second platform is allixed at the delivcry side of the first platibrmand has the outer edgethereof turned up as a rest, against which i the cut grain is delivered by the rake, and it thus serves to aid in compressing; the gavels into the forth fora sheaf, and the out grain is delivered therefrom by a rake-bend allixe'd to the exteriorend ofeoinponnd'eiongating levers,

which are operated by a cam on the crank shaft, and-their action is an adjusted as to deliver each gavel immediately upon its having been deposited on the second platform by the rake and while the rake is returning to the front of the platform for another gavel. Said second platform is marked P, the elongating levers are marked f, and said platform i's'so arranged as to be removable at pleasure with the elongating levers. that green or wet grain may be permitted to lie in loose travels to cure or to dry beforebeing bound.

Having thus set forth my i mode of operation, what I claim therein as new, and desire'to secure by Letters Patent, is-

l. The peculiar construction, location', and arrangement of the back-action rake. tbe'g'earing, and the mechanism for connecting them, in combination with the driving-wheel, platform, and main frame, substantially as described.

2. The arrangement of the compound elongating levers f f, operated by the eceentricon the shaft ll, in combination with the platform and the bnek-action rake or its equivalent, in the manner and substantially as described, for the purpose specified.

in testimony of which invention I have hereunto setmy hand this 9th day of May, A. I). 1860.
